¿Hay fuerza neta diferente de cero sobre un cuerpo que se mueve sobre una curva? Justifique

• Nonzero Net Force. – If the net force on an object is not zero, it is not in equilibrium (that is, a change in velocity will occur), and thus Newton's Second Law must be used to determine its motion. When the net force of the body is equal to zero, it implies that the body cannot be accelerated. This follows from Newton's second law of motion.

If the net force on an object is not zero, it is not in ... Example. Two forces A and B of magnitudes |A| = 3 N and |B| = 5 N are applied to an ...

Explanation: A plane will fly at constant velocity if the acceleration is zero. The forces are in balance. Consider a person sliding down a slide at constant velocity. In this example, there is no net force when a mass moves at constant velocity. A body is said to be in equilibrium if the net force acting on the body is zero. By Newton's second law, the acceleration of such objects will be zero. ... So an object in equilibrium can either have zero velocity or a constant non-zero velocity

explanation:

newton's third law, for every action there is an equal and opposite reaction.

wavelength divides in half and speed stays the same.
